I thought Ryanair were pulling out of Greece? I could see 2-3 per week to Warsaw-Modlin catering for the large Polish population in the area (mainly in and around Southampton though) Rome/Milan are not currently served from any of the south coast's ariports so they could be a good bet 3-4 per week and maybe Venice or even Porto a couple of times per week (Nermarket Hols and Palmair have shown theres some good demand to those destinations). The Greek routes would be worth considering is Ryanair are going to stay there too!
However its good to see almost all of their current routes doing very well especially considering the economy and an anti-aviation Government. I would imagine Thomson are doing well as they have kept all of this years routes for S13 plus re-added Tunisia but how have Aer Lingus and Blue Islands been loads wise?
